NAME
     env - run a program in a modified environment

SYNOPSIS
     env [-] [-i] [-u name] [--ignore-environment] [--unset=name]
     [name=value]... [command [args...]]

DESCRIPTION
     This manual page documents the GNU version of env.  env runs
     a  command  with an environment modified as specified by the
     command   line   arguments.    Arguments   of    the    form
     `variable=value'  set  the  environment variable _v_a_r_i_a_b_l_e to
     value _v_a_l_u_e.  _v_a_l_u_e may be empty (`variable=').   Setting  a
     variable to an empty value is different from unsetting it.

     The first remaining argument specifies a program to  invoke;
     it  is  searched  for  according to the specification of the
     PATH environment variable.  Any arguments following that are
     passed as arguments to that program.

     If no command name is specified  following  the  environment
     specifications,  the resulting environment is printed.  This
     is like specifying a command name of `printenv'.

  OPTIONS
     -_u, --_u_n_s_e_t _n_a_m_e
          Remove variable _n_a_m_e from the environment, if it was in
          the environment.

     -, -_i, --_i_g_n_o_r_e-_e_n_v_i_r_o_n_m_e_n_t
          Start with an empty environment, ignoring the inherited
          environment.

     The long-named options can be introduced with `+' as well as
     `--',  for compatibility with previous releases.  Eventually
     support for `+' will be removed, because it is  incompatible
     with the POSIX.2 standard.
